The European Corn Borer
No full textThe European corn borer was first recorded from South Dakota i n the summer of 1946. At that time Hr. H. C. Severin and the author found borers in corn in Union and Lincoln and Minnehaha counties. Less than half of one percent of the stalks in the fields were infested at that time. During the summer of 1948 the infestation had spread over most of the corn producing area of our state. By the fall of that year 36 counties were known to be infested . Several fields in the southeastern part of the state had 100 per cent of the stalks showing borer injury

The European Corn Borer Situation in South Dakota Spring 1952
No full textThe European corn borer, which has now assumed the role of perennial pest in South Dakota, has been conspicuous by its inactivity during the past few months. However, it is still the major pest of corn in our state. Since last fall the larvae (worms) have been spending their time in the deep freeze sleep of their kind of hibernation, hidden away in the snow-blanketed stalks of last years corn fields. This is nature\u27s way of taking care of them during the winter, and all too many of the larvae are now becoming active again
Tillage Methods in Grasshopper Control
No full textDuring the past 88 years of agricultural history in South Dakota, 38 have been years in which grasshoppers were present in above normal numbers. During 17 of these 38 years grasshoppers have been a serious pest of agricultural crops in South Dakota and neighboring states. Many millions of dollars worth of cereal, forage and truck crops during each of these 17 years were destroyed by hungry hordes of the insects. The impetus given soil conservation work and farm woodlot and shelterbelt plantings of trees in the past few years has brought about the realization that grasshoppers are far more than just a serious menace to growing vegetation. In areas where hoppers appear in outbreak numbers they are, through the destruction of growing plants, very definitely one of the major hazards of the soil itself. Under dry conditions and a lack of vegetative cover the soil in restricted portions of South Dakota and other Great Plains states is subject to devastating 0rosion by wind. The dust storms of a few years ago, fences buried by drifting soil and eroded wastes where cultivation was attempted in once fertile prairies--all bear mute testimony to this statement. Drought and improper treatment of the soil have been two of the important long-time factors in bringing about these conditions while grasshoppers have been one of the most important immediate factors
The Use of Aircraft in European Corn Borer Control
No full textThe European corn borer is at present considered to be the No. 1 insect pest of corn in South Dakota. It is now known (by specimen records) to be present in every county east of the Missouri river and in Lyman, Gregory and Tripp counties west of the Missouri River in South Dakota. During 1948 the corn borer did an estimated 7,545,000
